Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for indicating rate of ice accretion part-icularly for use in an aircraft, the apparatus including test surface on which ice forms in use.  First and second gas conduits are supplied with gas from a common pressure regulator the inlet of which communicates with a gas supply.  A control port of the regulator is supplied with a reference pressure signal and the regulator operates to maintain its outlet pressure at a pre-determined amount in excess of the reference pressure.  Each of the first and second conduits includes a restrictor and each conduit terminates at its end remote from the regulator in an orifice.  The first orifice is adjacent the test surface and a pressure difference sensor is associated with the first and second conduits to produce a signal dependent on the pressure difference at points between the orifice and restrictor of the two conduits.  The pressure difference signal is applied to an indicator.  A control conduit connects the control port of the regulator to the second conduit at a point which is intermediate the orifice and the restrictor of the second conduit so that the reference pressure for the regulator is derived from the second conduit between the restrictor and the orifice thereof.  The test surface is moved relative to the first orifice at a predetermined speed and thus the first orifice will be restricted to an amount dependent upon the thickness of ice forming on the test surface.          The difference in pressure sensed by the sensor is directly related to the thickness of the ice layer on the test surface, and since the test surface is moving at a predetermined speed then the indicator indicates the rate of ice accretion on the test surface.

Abstract: SPECTRAL ANALYSIS ELECTROMAGNETIC           SURVEY SYSTEM     Abstract of the Disclosure:           A method and apparatus of detecting geophysical anomalies, particularly those in sulphide-carrying ore bodies are disclosed.  The invention provides for the generation and transmission of one or more substantially pure sine wave signals from a transmitting coil at a frequency in the audio range, especially in the lower end of the audio range; and sampling the receiver coil for the presence of a secondary field -- i.e., a signal other than from the transmitter coil and at a harmonic frequency of the fundamental sine wave frequency of the transmitted signal.  In general, the trans-mitter and receiver coils are minimum-coupled so as to preclude the likelihood of pick-up by the receiver coil of primary field; and also, in general, the fundamental frequency of the pure sine wave being transmitted from the transmitter coil is not sampled or is rejected by the sampling circuits.  Because the fundamental frequency is not sampled or is ignored, and because the fundamental frequency is a substantially pure sine wave, there is substantially no noise problem in respect of detected secondary field signals indicative of a sulphide-carrying ore body.

Abstract: ABSTRACT OF THE DISCLOSURE A sensor responsive to the partial pressure of oxygen and suitable for inclusion in an internal combustion engine exhaust gas environment is disclosed.  The sensor is comprised of a ceramic material fabricated from an alloy of cobalt monoxide and magnesium oxide.  The ceramic material exhibits, at elevated temperatures, a direct and generally linear change in the logarithm of it  electrical resistance as a function of the partial pressure of oxygen.  A body of the cobalt-magnesium monoxide ceramic material is supported by a housing formed of a compatible nonreactive, ceramic material such as alumina.  A pair of electrical leads communicate the sensor ceramic body with an external utilization device.  The external utilization device may be arranged to measure the change in resistance of the ceramic sensor body in response to its environment.  When the sensor is situated in the exhaust system of an internal combustion engine or a furnace, the change in electrical resistance of the sensor ceramic body is a measure of the partial pressure of oxygen within the exhaust system and is also indicative of the air/fuel ratio of the combustion mixture which has produced the exhaust gases of the sensor's environment.  In a preferred embodiment, the external utilization device is arranged to modulate or control the air/fuel ratio of the combustion mixture in response to the sensor.

Abstract: ABSTRACT OF THE DISCLOSURE          In all forms the expansion valve regulates the flow in accordance with the pressure in the diaphragm head chamber as affected by the sensed temperature.  To prevent excessive inlet pressure a plug valve operated by a piston modulates the flow which reduces the flow through the system and thus reduces the output of the compressor causing the high side pressure to drop.  The piston is exposed to the inlet (high side) pressure and to the outlet (evaporator) pressure (which remains relatively constant) or to a substantially fixed pressure.

The process consists essentially of chopping the material to break it into a finely divided particulate and homogeneous mass; depositing the material as a finely divided particulate homogeneous mass on linearly spaced flat reciprocating transporters housed within a at the other, including the step of material the material as it is deposited on the transporters; transporting the material through a vaporizing zone in direct contact with the transporters which are made of electrically heated material, electrically heating the transporters to thereby heat the petroleum bearing material as it is transported through the vaporizing zone to vaporize the corresponding component of the petroleum and then recovering the said corresponding vaporized component of the petroleum as a distinct condensate. Even though, the vaporizing zone may be singular. it may be, if desired, divided into a plurality of vaporizing zones, corresponding to the member of hydrocarbon fractions which it is desired to separately collect in a substantially pure state. In the case of a series of vaporizing zones, the temperature to which the material is raised in each chamber is that at which the particular fraction to be recovered is vaporized.

Abstract: ABSTRACT OF THE DISCLOSURE            A machine for "dry mix" packerhead concrete pipe manufacture has two stations and a separable tubular jacket movable there-between.  A rotatable cylindrical packerhead is movable axially within the jacket and a "dry mix" delivery means deposits mix atop the packerhead as it rotates and moves vertically upwardly within the jacket.  The packerhead distributes the mix there-about to form a concrete pipe in the jacket.  A radially expan-dable and contractable core is movable axially in a contracted condition to a position within the pipe and is then expanded. Vibrators within the core are operated to "redensify" the pipe; that is, to compact the mass thereof, to eliminate voids, and to relieve residual forming stresses therein.  A guide ring is employed to align the contracted core axially with the pipe during entry and further guiding and supporting devices for the core are provided.  Core entry and withdrawal is power actuated as is core expansion and contraction within the pipe.  Expan-sion and contraction devices may comprise fluid cylinders oper-ated adjacent a single axial split line in the core or, true circle expansion and contraction means may be provided with a core having one or more axial split lines.
